CURRENTS: FRONTIERS; Your Very Being, Saved on a Swab For All Eternity

Can't quite come to terms with leaving this mortal coil? The DNA storage and profile request pack ($29.99, right, for one test) from CATGee, a London-based company, offers part of you -- your genetic code -- immortality. Included in the kit (which also comes in two- and four-test sizes) is a sterile swab to be swiped on the inside of your mouth, then placed in a special storage card (for safekeeping). A second swab can be sent to a laboratory for DNA profiling (for an additional fee of $59.95 -- envelope included). CATGee suggests using the kits to diagnose or cure the diseases of future generations, identify your remains after a disaster, or identify kidnapped children. David Nicholson, the company's founder and owner, says that ''confidentiality is assured.'' The kit can be found at Basics Furniture, 92 Seventh Avenue (15th Street), New York, (212) 691-5595; other retailers are available at www.catgee.com.
